SHIPS-BOTTOM PAINT.

1,200,162. Specification of Letters Patent.

No Drawing. Application filed August 7, 1915. Serial No. 44,200. g/ I To all whom it may concern:

Be it known that I, HENRY G. BReoKIrI, a citizen of therUnited States, resldmg in the city of Newport News, county of War-. wick, State of Virginia, have invented a new and useful Ships-Bottom Palnt, of

which the following is a specification.

My invention consists of a novel ships bottom protection covering composition, and

relates to paints specially applicable to ship bottoms, particularly below the water hne, not only for the purposes of decoration, but

more particularly to protect the surfaces I combine the above pigment with a vehicle containing a mixture of denatured alcohol, shellac, tar oil and petroleum spirits, the proportions whereof maybe varied somewhat according to requirements, my resultant novel composition of matter containing the following ingredients,iron oxid, zinc oxid, silica, magnesia, pine tar oil, petroleum spirits, denatured. alcohol and gum shellac. If desired, I may employ a ship bottom paint having the same pigments .and same amounts with a vehicle containing the follcfiwing,resin varnish, benzin and pine tar o After applying the foregoing composition or paint to the ships bottom, apply thereon the following novel composition or antifouling paint, which paint is especially applicable to prevent marine growths of allkinds, and is composed of the following ingredients:I employ a pigment containing iron oxid, silica, lime, zinc oxid, magnesia and mercuric oxid, the same being ground in a suitable mill. With this pigment, I

combine a vehicle containing alcohol, shellac, tar oil and petroleum spirits, the proportions which I preferably employ being .varied according to requirements, the resultant composition being as follows,iron ox d, zinc oxid, silica, magnesia, lime, red ox d ofmercury, pine tar oil, petroleum spirlts, denatured alcohol, and gum shellac.

The term petroleum spirits is the tradename for a distillate manufactured from Texas petroleum, which distillate is free from solid paraflin and has a gravity of 42.2 Baum, flash test 105 to 110 F., and an evaporation test of about 25 minutes.

If desired, I may employ an anti-fouling paint having the sameamount of pigments with a vehicle containing resin varnish, benzin and tar oil.

, It will now be apparent that I have devised a novel and useful ship bottom paint,

which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment there- 'of which will be found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advanta es.

Having thus described my invention, w at I. claim as new and desire to secure by Letters Patent, is

1. A paint comprising a pigment of iron oxid, silica, zinc oxid and magnesia commingled with a vehicle containing a mixture of denatured alcohol, shellac, tar oil and petroleum spirits.

I 2. The herein described paint comprising iron oxid, silica, lime, zinc oxid, magnesla and mercuric oxid, with a vehicle contaming alcohol, shellac, tar 011 and petroleum spirits.
